Hi, GD's, I tried to use ID3DXLine::SetWidth to set the width of a line, but this function always returns error. I have tried many values: 1.0f, 2.0f, 5.0f.... Anybody has an idea? Thanks a million! Dan

uhhm, what error?! [smile]

As in, give us some more details - whats the return code? Or, you can probably help yourself by using the debug runtimes - if you're mis-using a function the debug runtimes will scream and shout at you as to what it doesn't like (invalid parameter etc..). See the link in my signiture if you're not familiar with the debug runtimes.

If I remember correctly, you have to set the line width outside of the Begin() / End() pair. I did that once before and got the behavior you described.

Are you setting the width before begin?

line->SetWidth(x);line->Begin();line->Draw(...);line->End();

I'm not sure if calling SetWidth after begin would cause an error, but it wouldn't change the width.

Thanks, everybody.

Putting SetWidth outside Begin/End works. hahah, so happy.
